An exercise assembly for selectively providing resistance to a user’s hand includes an article of apparel that may be worn on a user’s hand. In addition, this invention provides for the catching and retrieval of the suture after it is passed through the tissue. When an antenna is connected normally, a pulse AC signal is transmitted to an output terminal via the antenna, and current flows from the output terminal into the capacitor via a resistor, a diode, and a resistor. The generator circuit also includes a generating circuit coupled to data loading circuit for receiving a plurality of periodic pulse width modulated signals, and for generating a pulse width modulated signal by combining each constituent pulse width modulated signals that correspond to a data bit in the data word that indicates the selected state. The retardation films are single-axial films.
